I have some problems which I have not seen before, because I simply didn't need to use a USB device before now.
But in short, when I plug in my USB pen, no block device will be created in /dev (like sdb, sdc etc. ...).
Here is the info I find relevant:
I'm using the zen kernel (kernel26zen-git found in AUR) with a custum kernel config, however it doesn't work in the standard -ARCH kernel either with the standard kernel config.
All the modules seems to be loaded according to lsusb:
[joey@Kessler ~]$ lsmod | grep usb
usbhid 41728 0
hid 35268 1 usbhid
ff_memless 4488 1 usbhid
hci_usb 12572 0
bluetooth 47108 1 hci_usb
usbcore 127728 5 uhci_hcd,ehci_hcd,usbhid,hci_usblsusb seems to know it's existence:

Hi there,
After inserting my usb pen, here's my modules
$ lsmod | grep usb
usb_storage 85440 0
hci_usb 13980 0
usbhid 43584 0
hid 39424 1 usbhid
ff_memless 5000 1 usbhid
usbcore 131248 5 usb_storage,hci_usb,usbhid,uhci_hcd
scsi_mod 94700 4 usb_storage,sg,sd_mod,libataSo I'd try again after
# modprobe usb_storageHope it helps.
EDIT:
I assume you've created your rc.conf MODULES array with
$ hwdetect --modulesYou might want to do it again with your usb pen attatched to get all relevant modules listed.
EDIT 2:
I didn't notice until now you've blacklisted scsi_mod and sd_mod in your MODULES and they seem to be needed too..

Oh yeah I will try that when I get home.

That could be a problem. I can't simply find those modules in the zen kernel - even if I just use the standard kernel .config that comes with the kernel26zen-git PKGBUILD. In short I don't know witch option "turns" these modules on.

Could be that they're built in the kernel image instead of built as modules.

I don't know. When I try search after those modules in makeconfig I can't find them anyware - or I just don't know what they're called.

Loading usb_storage worked alright. Don't seem to need scsi_mod and sd_mod at all.
